Anyone know the clearance needed for 31in tires? Ive seen many similar posts but regarding different sizes and setups. On a budget and basically just want to replace my worn shocks and whatever else to fit these tires w/o rubbing issues. Any advice?

Thanks! I did some more research and came to the same conclusion. I have a 2in Daystar BB enroute and four 245/70R17 GY Wrangler MT/Rs in the garage. Hopefully I'm good to go I know the Overland has the Up Country suspension which supposedly gives it an extra inch. I'm wondering if that's in the springs. If so, that means I'll actually have a 3in lift?

Yeah like I said, 2" on a ZJ will fit, but the WJ with it would be fine too as they are similar in most ways. If your springs are 1" longer than yeah, you'd have 3" lift over the stock height, more than enough for that tire!

The UpCountry is a 3/4" lift over the standard suspension and is standard equipment on the 2002 Overland. Starting in 2003, it was a frequently (accidentally) deleted option and in 2004 it was eliminated altogether.

HOWEVER... WJ springs are known for sagging so you may not be at the original ride height... in fact some people are as low as 1.5" lower than stock after 10 years. Another contributing factor is the OEM spring isolators. In the WJ, they added rubber supports on both ends to reduce vibration and harshness from the solid axle suspension. They collapse. A lot. In my WJ, replacing them was good for an additional 3/4" of ride height. www.rockauto.com has very good pricing on them, as does Kolak (vendor here).

Usually we recommend spring lifts over the Budget Boost to eliminate the sagging OEM springs, improve ride/handling, and give better flex off-road. However, bang-for-the-buck is hard to beat with coil spacers.

Here's my epic post on the 2" spring lift. Even if you are just doing a BB, a lot of people have found this how-to very helpful.

Very interesting. And epic post indeed! Seriously considering the springs and isolators. Quick question though. Could you combine both a BB and spring/isolator replacement and what kind of results have you experienced or heard about this? Sorry if it's been answered already in your thread. Army has me working stupid hours so I'm getting kind of lazy.....

Yes when you install a BB you reuse the isolators, in your case you may just want to buy new isolators when you install the kit. A new set of isolators will make for a little smoother and quieter ride so it's highly recommended.

Sorry, for some reason my JF notifications weren't getting emailed over so I didn't get your question till today.

My final configuration with the 2" lift was to add the 2" springs, Bilstein shocks, new spring isolators all around, and 3/4" spacers up front. In the suspension, I added longer sway bar end links in the rear, Rough Country disconnects up front, and a JKS track bar and JKS tie rod. The 3/4" spacers made the WJ look more level (the rear fender flares are higher than the front). It also gave a little more height which is lost when I have my winch on the front (it's a multi-mount, can remove it when I want to).

You technically CAN mount 2" spacers on top of 2" springs but its not a very good idea. It's not as simple as just putting in the spacers and springs and calling it good. WJ lifts start getting more complex and expensive at 4". You need longer shocks, longer front control arms, rear a-arm spacer or new a-arm, longer sway bar end links front/rear, longer/adjustable track bar, driveshaft (on some WJs). If you really want a 4" lift, then sell/return your spacers and buy a mostly-complete kit which has most everything you need at a better price than piecing it together. A very popular 4" lift is the Zone Offroad kit, starts at $700, and has a lot of good reviews for ride/install. The cheaper kits are less complete and lower quality, in my opinion, good 4" lifts start around $700 and GREAT ones are $1000+.

Hope this helps.

This helps greatly. You seem to know your stuff. What would you say are absolute necessities and why if doing the 2in spring lift (Sway bar end links, disconnects up front, track bars and tie rods and 3/4" spacers?) I'm looking to keep my 2in lift simple and affordable since I don't do serious off roading. Just the occasional beach bugging and traveling off the normal hike trails. I also want to level it out and be able to fit my MTRs under. Plan to do it with a friend and keep it under $500 if possible.

Necessities at a 2" lift... if you are still using those Daystar pucks, put some good 2" lift shocks on there and that's all you NEED. I would recommend putting in longer rear sway bar end links though, it really helps out the ride because the rear sway bar sits at a really bad angle at 2" lift. It binds up on bumpy turns and gives you the head-toss-side-to-side rocking that is really uncomfortable.

Unfortunately, no one seems to sell a 2" longer end link. I had someone lengthen the stock ones, just cut and weld in a sleeve to make them 2" longer. Helped immensely. All the other stuff is nice, but isn't NEEDED at 2" lift.

So same answer if going to the spring lift instead of spacers? Think I'm switching.

My frien has 31" pro comps on his 97 ZJ no lift nothing. All he had to do was trim his front bumper. I'd assume that it would work on the WJ too? It looks good might I add. As long as you don't mind tucking tires!!
